Anthony Smith, 26, was charged with first-degree murder in the Sunday morning slaying of Hansen Jackson, police said in a news release.

After hearing gunshots near the intersection of Chicago and Ridgeway avenues just before 2 a.m. Sunday, police officers actually saw Smith fire multiple shots at the 29-year-old victim, authorities said.

The officers arrested Smith after a blocklong foot chase and recovered a handgun, authorities said.

Jackson, 29, of the 1500 block of South 61st Court in Cicero, was struck multiple times and taken to Mount Sinai Hospital, where he was later pronounced dead, according to the Cook County medical examiner's office.

Gunned down across the street from an anti-violence mural, Jackson was one of 15 people shot -- and second fatality -- during between Saturday night and early Sunday morning.

Police didn't offer a motive for the slaying.

Smith, of the 9000 block of South Wallace Street, had been out on parole since last November from the Robinson Correctional Center following a 2007 conviction for attempted first-degree murder, according to court and state records.

After pleading guilty, Smith was sentenced to seven years in prison and ordered to serve 85 percent of his sentence, but he was credited with 621 days served in Cook County Jail leading up to the trial, records show.

A Justice Department investigation will allege sweeping patterns of discrimination within the Ferguson, Mo., Police Department and at the municipal jail and court, a law enforcement official familiar with the report said Tuesday.
